Well, all DNA in humans form double helices. However, the genetic material for mitochondria does not take up an entire length of DNA. The gene for mitochondria will only take up a very small site on the DNA molecule. U get my point? I sure hope this was useful.
----------------- All human DNA is double helical. Single-stranded DNA is only used in viruses as genetic material. Mitochondrial DNA is also very small and circular compared to chromosomes, which are extremely large and linear.
It just is; there really isn't a "why". It's a result of the way chemistry and physics work. By the way, it's not just humanDNA that forms a double helix; it's a property of DNA generally.
helical spring
Yes, helical viruses have a rod-shaped structure. These viruses consist of a cylindrical or helical capsid that encloses the viral genetic material, which can be DNA or RNA. The helical capsid gives these viruses their rod-shaped appearance.
Watson and Crick proposed the double helical structural model of the DNA
I believe so, because I think she took the picture that showed that DNA had a double helix pattern.
The double helical structure was discovered by Watson & Crick.
DNA in its native form is double-stranded and helical.
All nuclear DNA in eukaryotes is linear DNA. Eukaryotic chromosomes, such as those in human cells, are linear DNA molecules spooled around support proteins called histones.
Of course not,DNA consist of two helical chains
It suggested that the structure of DNA was helical.
helical structure of DNA
DNA is double helical (like a step ladder) in structure
Pattern of basics between two helical chains of a DNA

Double helical structure
DNA in Eukaryotic cells are linear. DNA in Prokaryotic cells are circular.
Yes, helical viruses have a rod-shaped structure. These viruses consist of a cylindrical or helical capsid that encloses the viral genetic material, which can be DNA or RNA. The helical capsid gives these viruses their rod-shaped appearance.
the parts of DNA are: phosphate nitrogenous base(adenine, guanine, thymine and cytosine) hydrogen band helical protein
